The forward ends of the Webs lnre united by e trnnsversely disposed webor nieto 25, which, when the device is properly applied. for use,engages directly against the rear side of the end sill 12, end formed-intee'rsl with the forwerd ends of the draft arms is 's transverselydisposed late A27 which engages directly egsinstt e front fece of theend sill.` yThe ends of this plate 2T ere reinforced by boes- 28, thesame being; perforated inorder to receive the ends of truss rods 29which extend in the usuel inf-nner from one end sill to the other.

The construction just described not only provides very ,substantielwashers for the of the tram rods end prevents the nuts from pullingintoA the end sill, but also the entire cor together from end to 'endugh the draft arms end sill reinforcesnd seid truss rods.
